[Psychological aspects of orthognathic surgery]

Corrective jaw surgery, for patients with malocclusion and dysgnathia, is primarily performed to rehabilitate oral functions. However, the patients' motivation for orthognathic surgery often seems to be influenced as well by the desire for aesthetic correction of a facial anomaly. Preoperative screening for psychiatric problems such as body dysmorphic disorder is requisite. The majority of orthognathic patients experience a negative influence of their appearance on their psychosocial well-being. In addition, the hope for aesthetic improvement is not seldom an important incentive for visiting an oral and maxillofacial surgeon. In the literature, in addition to a positive effect of corrective jaw surgery on the patient's perceived appearance, an associated improvement in quality of life is described. Correction of a disharmonious face is at least as important to patients as oral function recovery.
